Jessica O'Connor and Dion Reynolds, both 23, set off on May 9 but haven't returned.

It's believed they entered the national park near the Anatori River carpark.

Police searched the area today without luck, with the search set to resume tomorrow.

Ms O'Connor's father, Mark O'Connor, is hoping the two are found safe.

"We are hopeful for Jess and Dion's safe return and really appreciate all the people that are involved in the search," he told 1 NEWS.

Police are asking for anyone who may have seen the pair to get in touch, especially anyone who's been around the Anatori, Webb, Kokopu, Independent and Fraser rivers since May 8.
